Abstract

Un elemento di sopporto dorsale, preferibilmente lombare, (1) per sedili quali sedili automobilistici, presenta una generale configurazione a clessidra o farfalla ed è costituito da due parti complementari (3), simmetriche fra loro. Ciascuna di dette parti è sostenuta su uno dei montanti (7) dello schienale (B) tramite un tirante (4) orizzontale, che si estende attraverso un'apertura (11) provvista in una parte a bandiera (8) incernierata (9) all'estremità esterna della rispettiva parte complementare (3). Mezzi di trazione, quale comandi a cavo flessibile o bowden (13), consentono di richiamare verso l'esterno le estremità libere delle parti a bandiera (8). Per effetto del divaricamento delle estremità libere delle parti a bandiera (8) così ottenuto, le estremità esterne delle parti complementari (3) vengono sospinte in avanti, modificando il profilo orizzontale dell'elemento di sopporto (1) verso una condizione di maggiore concavità, rendendo più spiccata l'azione di contenimento laterale attuata dallo schienale (B). (Figura 1)A back support element, preferably lumbar, (1) for seats such as automotive seats, has a general hourglass or butterfly configuration and consists of two complementary parts (3), symmetrical to each other. Each of said parts is supported on one of the uprights (7) of the backrest (B) through a horizontal tie rod (4), which extends through an opening (11) provided in a flag part (8) hinged (9) to the external end of the respective complementary part (3). Traction means, such as flexible or bowden cable controls (13), allow the free ends of the flag parts (8) to be called outwards. As a result of the separation of the free ends of the flag parts (8) thus obtained, the outer ends of the complementary parts (3) are pushed forward, changing the horizontal profile of the support element (1) towards a condition of greater concavity, making the lateral containment action implemented by the backrest (B) more pronounced. (Figure 1)
